Was this for business? or personal?
Either way, they will love it, I think you did a nice job!
Any comments to add might be adding in some natural audio I think would make it much better. Especially of the service by the officiant/priest/(dude with the robe).

I thought the song had a very nicely matching child like innocence to it, so good job on that.

Thanks for your comment. I took your advise and added some natural sound at the important part of the ceremony where the priest actually christens Irene. This was for business and I also hope that the clients will like it.
